the UK is on a fiscal tightrope. the steadier the rope, the more room to move forward.
The Tightrope Score runs from 0 to 100: higher means more room to move, lower means the rope is closer to giving way. Markets, fiscal headroom, the labour force, and growth delivery each pull on the rope; the score is the geometric mean of those four pillars. Every number sourced and open.

Market stability
The daily market read on UK constraint: long gilts, sterling, the rate path, mid-cap equities, and the energy input.
Gilt curve anchors
10y and 20y zero-coupon yields, breakeven inflation, and risk assets.
Market stability trajectory
30-day pillar score. Higher = more market stability; lower = more constraint from markets.
Scored 30 of 30 days.
Why this matters
Long gilt yields are the price the Government pays to borrow. When they rise, debt service bills rise with them, the Chancellor's fiscal headroom shrinks, and sterling often weakens — compounding inflation via imports. The 20-year zero-coupon yield is the clearest long-duration read on the BoE curve, and it is the one that moves first when policy credibility is in question.
Fiscal room
How much room the Chancellor actually has against her own stability rule, and how that has moved between forecast rounds.

OBR forecast rounds, BoE decisions, Budget set-pieces, and the geopolitical shocks that landed in between. Pinned to primary sources.
Renewed US–Iran tensions push gilts to a four-week high
Fresh US strikes and a declaration that the ceasefire is over send crude to two-week highs and reignite imported-inflation fears. The 10-year gilt yield climbs about 10 basis points on the week to print 4.95% on 9 July — its highest in four weeks — as money markets move to price at least one Bank of England rate hike by year-end, with roughly one-in-four odds of a second. The leadership transition due mid-month keeps a domestic risk premium in the curve.
Trading Economics (market report) ↗Nigel Farage resigns his Commons seat via the Manor of Northstead
The Chancellor of the Exchequer appoints Nigel Paul Farage as Steward and Bailiff of the Manor of Northstead — the procedural mechanism by which an MP resigns their seat, as Parliament does not permit direct resignation. The Reform UK leader leaves the Commons ten weeks after his party's historic local-election gains and days before the Labour leadership contest concludes, adding a further by-election to the political calendar during the transition of power.
HM Treasury (gov.uk announcement) ↗Prime Minister announces resignation; gilts and sterling wobble, then steady
Keir Starmer announces he will resign as Labour leader and Prime Minister once a leadership election concludes, following the May local-election defeats and the Makerfield result. Markets, having largely priced the outcome, react modestly: sterling slips to around $1.32, the 10-year gilt yield prints near 4.85% intraday before easing, and attention shifts to whether the next government maintains the current fiscal rules. Nominations open 9 July with a new leader due before Parliament returns in September.
Al Jazeera (contemporaneous report) ↗May borrowing overshoots the OBR profile at £23.3bn
Public sector net borrowing comes in at £23.3 billion for May — £5.6 billion above the OBR's monthly profile, driven by higher-than-anticipated central government spending. Borrowing for the financial year to May reaches £46.3 billion against a £38.6 billion forecast. The overshoot lands in the middle of the leadership contest and sharpens the question of how much fiscal headroom survives to the autumn statement.
Office for National Statistics ↗Andy Burnham wins the Makerfield by-election
Greater Manchester Mayor Andy Burnham wins the Makerfield by-election, defeating Reform UK's Robert Kenyon and returning to the Commons; he resigns the mayoralty the following day. The contest, triggered by Josh Simons' resignation on 14 May, is widely read as positioning Burnham for a leadership challenge — four days later the Prime Minister announces his resignation.
House of Commons Library ↗Bank of England holds Bank Rate at 3.75%
The Monetary Policy Committee votes 7–2 to hold Bank Rate at 3.75%, with two members preferring a quarter-point rise. CPI inflation has eased to 2.8%, but the Committee expects it to rise later in the year as higher energy prices pass through — global energy costs have retreated since May yet remain above pre-conflict levels and volatile. The hold keeps the rate path data-dependent through an energy shock the MPC cannot look past.
Bank of England ↗Gilt yields post biggest weekly drop since 2023
Gilt yields fall the most in a week since late 2023 as the pressures of mid-May unwind together: Andy Burnham commits to the government's existing fiscal rules, betting-market odds on a leadership change recede, and oil falls on optimism over US–Iran talks. The 10-year eases roughly 30 basis points from its peak toward 4.85% — a five-week low by 26 May — and the 30-year falls over 30 basis points on the week, while traders price one fewer rate hike for 2026.
CNBC (contemporaneous report) ↗10-year gilt yield peaks at 5.14%, highest since 2008
The 10-year gilt yield peaks at 5.137%, its highest since July 2008, with the 30-year touching 5.86% — territory last seen in 1998. The sell-off combines a global rout in long-dated government bonds with a UK-specific political risk premium: a cabinet resignation the day before and open speculation about a leadership challenge revive memories of 2022's fiscal-credibility shock, and long maturities bear the brunt through higher term premia.
Reuters (via Yahoo Finance) ↗Local elections: historic Labour losses as Reform UK takes 12 councils
English local elections across 136 authorities deliver the largest gain by any party outside the big two in local-election history: Reform UK wins over 1,050 seats and control of 12 councils. Labour loses roughly 340 councillors, seven councils held since the 1990s, and finishes third in equivalent vote share for the first time. The result intensifies pressure on the government's delivery agenda and begins the sequence that ends in the Prime Minister's June resignation.
Rallings & Thrasher / LGC ↗Oil tops $118 as Hormuz blockade escalates
Brent crude rises for an eighth straight day to top $118 a barrel after the US President pledges to blockade Iran until it agrees a nuclear deal, touching $126.41 the following day — the highest in four years. With the Strait of Hormuz (normally a conduit for around a fifth of global oil and gas) effectively shut, the energy shock feeds directly into UK inflation expectations and pares back priced-in Bank of England rate cuts.
CNBC (contemporaneous report) ↗March CPI rises to 3.3%, BoE path under scrutiny
ONS releases March 2026 CPI inflation data showing headline CPI at 3.3% YoY (up from ~3.0% in February), driven by lingering energy and petrol price effects from the Iran conflict period. Markets price in a more cautious BoE path ahead of the 30 April MPC decision; gilt yields stabilise but remain elevated.
ONS Consumer price inflation ↗Resolution Foundation: conflict could erase £16bn of headroom
Resolution Foundation warns that a prolonged or severe Middle East conflict could erase up to £16bn of the Chancellor's current-budget headroom — almost three-quarters of the March OBR cushion — via higher energy prices, inflation, and debt interest. Report highlights fiscal vulnerability even under the current ceasefire.
Resolution Foundation ↗Sterling recovers to pre-war levels
GBP/USD back near 1.2400 as the Iran ceasefire holds and Strait of Hormuz shipping normalises. Oil and UK gas sell off sharply. BoE officials nonetheless stress inflation control remains the priority.
Reuters, Bank of England ↗Reeves rules out tax rises or borrowing for extra defence spending
Chancellor tells reporters additional defence outlays up to the 3.5% commitment will not be funded by more borrowing or higher taxes, pointing the pressure back at welfare and departmental restraint.
Reuters, HM Treasury ↗US, Israel and Iran agree conditional ceasefire
US, Israel and Iran agree a conditional two-week ceasefire; UK Foreign Secretary and international finance ministers welcome the de-escalation, citing restored Strait of Hormuz shipping and falling oil and gas prices. Initial market relief begins, setting the stage for sterling's recovery to pre-war levels by 17 April.
Foreign Office / gov.uk ↗OBR Spring Forecast: headroom 23.6bn, GDP cut to 1.1%
Current-budget headroom ticks up from 22.0bn at the November Budget. 2026 growth downgraded from 1.4%. IMF subsequently cuts to 0.8% citing the Middle East shock.
OBR, IMF ↗Iran conflict begins, energy shock lands
UK natural gas front-month jumps 38% inside a week. 30y gilts break 5.5% for the first time since 1998. Tightrope Score moves from 51 to 68 over four trading sessions.
